SPECIFICATION forming part of Letters Patent No. 239,852, dated April 5,1881.

Application filed February 19, 1881. (ModeL) To all whom it may concerning-rails of the upper and lower sashes; O, the

Be it known that I, LEICESTER SARGENT, of base-plate of the lockingmechanism, which is New Haven, in the county of New Haven and attachedto the lower sash. ()n this plate a State of Connecticut, have inventedanew Imdisk, D, is pivoted, as at a, and so as to turn provement in SashFasteners; and I do herefreely on the plate. A portion of the disk is bydeclare the following, when taken in concut away to form a straightside, d, which, nection with the accompanyingdrawings and when thedevice is in an unlocked position, the letters of reference markedthereon, to he lies parallel with the outer edge of the plate afull,clear, and exactdcscription of the same, 0, as seen in Fig. 1. The diskis also con- 10 and which said drawings constitute part of structed witha flange, E, projecting upward this specification, and represent, inandstarting from the straight side d, as at 0,

particularly to such as have a flange projecting Instead of making thelever or arm by which 7 up from the lever-hub, so as to be turned bethelocking is produced in the same piece with hind thecorrespondingprojection in the keeper the disk, and so as to move to thesame extent,

25 on the other part, and so that when the huh I make the leverLseparateand detached from is so turned it not only locks the sashestothe disk D, and pivot it to the plate 0, eccengether, but covers thejoint between the sashes, tric to the pivot of the disk, as at 11,preferably so that it is impossible to introduce an instruoutside of thedisk-pivot a, and I construct the ment between the sashes to operateupon the disk with a slot, at, eccentric with its pivot to,

, o fastening device. and through which the pivot l of the lever eX- Inthe'construction of fastener with a hub tends, to be fixedin the plate0, and so that provided with a flange above described it is the disk mayrevolve freely, the slotn passing necessary to give a half-turn to thelever and the pivot l of the lever. The outer end of the hub-that is, toturn the lever from its position lever is shaped in any convenienthandle form,

5 of rest at one side to a diametrically-opposite the inner end, P,provided with a stud, r, 8 point. In such construction the position ofwhich enters a corresponding radial groove, 8, the lever does not fullyindicate the" fact of in the disk, the arrangement of the groove .9whether or not the sashes are properly fastand the stud r being suchthat when thelockened, because the lever presents a full side ing deviceis in the unlocked position the le 0 view in either position, and not,as in other ver stands substantiallyparallel with the sashfasteners, theside view when unlocked and end rail, as seen in Fig. 1. As the lever isturned view when locked. The object of this invento the front the stud1', working in the groove tion is to construct the locking mechanism so8, turns the disk faster, owing to the eccentric that while the requiredhalf revolution will position of the lever, and so that when the 45 begiven to the hub, the lever will be turned lever has been turned halfaround, or at right 5 but one-fourth revolution, as in the usualsashangles to the sash, as seen in broken lines, fastener; and theinvention consists in the con- Fig. 1, the full one-half revolutionrequired has struction as hereinafter described, and particubeen givento, the disk. larly recited in the claim. Instead of pivoting the leverL outside the 50 A and B represent, respectively, the meetpivot of thedisk, it may be inside, as in Fig.

2, the stud and slots being arranged at a point opposite, as in thefirst-described arrangement,

the essential feature of the invention being that the pivot of the levershall be concentric 5 to the pivot of the locking-disk, and connectionbetween the lever and the disk at a point on substantially the oppositeside of the pivot of the disk. By this arrangement the desirable andclearly defined looked and unlocked 1o condition of the fastener isindicated, and yet the full and required movement of the locking-disk isattained.

It will be understood that instead of an up-' Wardly-projeeting flangethe flange may be 15 made upon the under side of the disk, so as toproject downward; but the best results are attained by making it asabove described.

I claim- A sash-fastener consisting of the disk D, constructed with alocking-flange and a keeper, said disk centrally pivoted to thebase-plate, combined with a lever pivoted to the baseplate through aslot in the disk, and connected to the disk by a stud moving in a slotin said lever at a point opposite said lever, sub- 25 stantially asdescribed.
